^C
Here is a simplistic answer to something you probably have figured out.
Hope this grep -nR helps you find , which *.h file got left out or modified
Here are 2 places IUTF8 are defined.  Now to figure out why they were not
included.  You have to just run the preprocessor on the C code base, and then
look for what DID NOT GET defined,   Fred
